Tool/software: Code Composer Studio

Hello

I'm using XDS200 and CodeComposer 8.3.1

I've noticed that writing file to host computer is very slow. It takes 1 second to do the following

1)open file using fopen

2) write "Hello\n" using fprintf

3) close file using fclose

is that normal? I dont think so

I update xds200 firmware by running 'update_xds2xx.bat xds200'

new version is 1.0.0.8

Any ideas?

Regards,

Fabio

Fabio,

This is expected, as Console I/O functions can be a lot slower than direct memory access operations. Also, they are dependent on the code optimization on the target.

For additioanl details, check the JTAG Benchmarks at:
